The Foreign Secretary's seat is also being changed, but Boris Johnson seems likely to stay as an MP

The big story as far as Conservative seats is the abolition of George Osborne’s Tatton constituency, while Foreign Secretary Boris Johnson’s Uxbridge and South Ruislip seat faces a substantial redrawing of the electoral map, but he would appear well-placed to secure the Conservative nomination for the new seat of Hillingdon and Uxbridge.

Labour has signalled it will fight the "unfair, undemocratic and unacceptable" changes, stressing they are based on an "out of date" version of the electoral register based on populations recorded in the electoral roll for 2015 and missing two million voters who signed up to vote in the EU referendum.

Mr Ashworth said: "The current proposals to redraw constituency boundaries are unfair, undemocratic and unacceptable.

“They are based on an out-of-date version of the electoral register with nearly two million voters missing.”
